The upper periphery 'ofthe base is rabbeted gas indicated at 5, to receive a bowl shaped c sbs t on hic on t c s' h p .Qf thestov Th gr t 3& s pp the bottom of this bowl, as clearly shown in the drawings. Thesdrumi or main outer "side wall offthe' stove preferably of sh'eet meta and mon te n o e n 'P .g 'periphe y of h 'bqwl, m m a also. as glgarly shown. The upper end lpf the drum is closed by a suitable top whichisprovidedv vfith a flanged sinoke' oiitlet -9,; upon Within fthelQWer' end f r the drum and rising upon the vupper edgeof the bowl 6; there i aT' 'iBg W1 iQ "i i mre etrthe front of the stove toreceive a mainfitted door 12, which .is' inset throngh the drum and at its lower edge 'mounted'updn the bowl 6. The door' 12 will ordinarily'be' provided with a damper control inleta s indi- "cated at 13.;

The intermediate part of the 'intenior of the drum is divided by a vertical-partition into front and rear "halves and said rear half v is again subdivided by a vertical partition n fi ip sa'ge 1? thi WM er zbe al .The numeral 16;

half disk partition 14 is mounted upon the upper edge of the ring 11, and in order that this partition 14 may be readily removable, it is made of two 909isegments, as shown clearly in Fig. 10. The front edges of these segments are provided with upstanding flanges 15.

vertical partition which divides theintermediate part of the drum into front and rear compartments. 7 This member 16 fits compartments or passageways. her-1191s supported at ts edges inguldes "at. its edges in grooved strips 17 applied to the inner wall of the drum, while at its lower edgeit is detachably connected to the upstanding flanges of the member 14:.

. 19,designates the partition member which c lividesithe rear .half of the drum into two This mem- 20,2l',, applied to the face of the partition 16 andjnterior; of the drum 7 respectively.

the other passage 23 is in free 'an'dope'n comspacexof the. stove in communication with f these return passages andthe return passages in. communication with each other, a. port or opening' '25 (see Fig. .6) is formed through; the upper part of thepartition member 16, and another port 26 is" formed through the lower part of the partition ,member 19. The lower port 26 is formed in the present instance by simply shorten-1:

the partition member 19.

in E Tn order to changethe stove from direct draft into an indirect draft, orvice versa, a half disk damper plate 27 vis mounted in 1 the upper part of the drum upon a pivot 28,

' .;and controlled by a rack and pinion so that" i it maybe shifted into either director indi- I the center thereof, where. they, overlap. The

.bll 'acketf29i is extended beyond the pivot 2 8, as'indicated at 31, and turned down to ,'-form a. guide for thejrack-I bar 32.

Thepinion33 is fastupon the damper plate, H r as= -best..seen inzFig; 7. Itwill be obvious @that when the damper plate 24-is position ..out1et ofthe stove, while upon turning the a'damper plate one-half around, the direct ces'followsr.

draft Will be completely cut ofi and anindirector return draft circulation established,

' I The gases of combustion fromthe fuel in the-fire pot will flow upwardly Mthrough Ethegf-IQllt half of the drum, thence rearwardly through the port 25 into downdesignates the transverse removed from the stove.

ream as my invention 5 1.v In aheating' stove,

take passages 22,thence' throughport 26 into uptake passages 23 and out through the open upper end of the latter into the upper space of the drum and through outlet of the latter. Of course, by shifting the damper plate 24 only partly, the circulation will be partly direct draft and partly return draft.

I An important feature of my -invention resides in the provision of a regulable amount of preheated-air discharged into the fire pot just above the fuel therein. At this endI provide. a conduit pipe 3 1 whichpreferably extends inwardly from the rear'sid'e of the drum just below the partition member 114;,

so the pipe is conveniently supported by wire as seen clearly in Fig. 1'. The inner-end of loop 35' (see detail Fig. 5) mounted upon the pair of bolts 36, which serve to hold the partition members 14 to the upright partition member 16. The inner end of said pipe is capped anduponiits' outerend is mount ed a damper body 37, the inlet of which is controlled by rotatable damper 38., f The'under wall ofthe: pipe :34 adjacentthe inner end is provided with a plurality 'o'f perforations 39 for directingflth airjsupplied' through the pipe 34 downwardly into the v fire box, the admission of air being dueto the draft through the stove andloutthe line 10, which serves to draw in'air through the pipe 3 1 and deliverlit downwardly todain mer body} of. the pipe and disconnecting" loop 35, said pipefmay obviously be readily v H By taking out bolts 36, the twosegments' whichfto gether v formed the horizontal positio nfl may also beremoved'from thestove andany dust or isoot collectedint'he pas gesf above said pan.

in the bottom of the chamber, f a partition at the top ofthe chamber above a portion of the bottom partition, vertical plates between the partitions, onej extending upwardly from the bottom partition terminating short of oneedge of the, upper pa'rti, tion and another extendingdownwardly .fromthe other, edge of the upper partition t 'ic mbi e i ie a fire"pot,-, a flue atthe upper'end of' 'the V stove, .a combustion chamber :tetweenwhe .to;-over lie therear half (of the drum and the returnigpassages therein, therewill be direct; .E'eommunication between the fire box and the .v n aitwi tfef w sereiu der ew th the details of'eonstrucition and arrangement .may be somewhat i modified without departtion directly over that covered by the lower segment and in the other direction to overlap that portion .of the chamber not embraced by the lower segment, to make a direct and indirect draft through the combustion chamber.

2. In a heating stove, a fire pot, a flue at the upper end of the stove, an intermediate combustion chamber, and means in the chamber to form a direct oran indirect gas passage therethrough; said means including partitions forming with the chamber wall a vertical passage open at top and bottom, a second vertical passage closed at the top and open at the bottom, and an intermediate passage closed at top and bottom with an opening in one wall at the bottom of the second passage and another opening in another wall at the top of the first passage; and a rotatable partition movable over the top of the first vertical passage to cause gas to pass through the intermediate passage and over the top of the second vertical passage to open the first passage for direct draft.

- 3. In aheating stove, a fire pot, a flue I at the upper end of the stove, a combustion chamber having partition means forming anopen draft passage, a secondrpassage open at the top and closed at the bottom, and an intermediate passage closed at top and bottom but having side ports, one connected with the top of the draft passage and the other with the bottom of the second passage, a pivoted partition member to swing over the top of the second passage or over the draft passage to cause direct or indirect draft, a pinion secured tothe pivoted partition member, and a rack engaging the pinion and extending without the chamber for rotating the partition.

4. In a stove, the combination of an upright casing having a fire box at the lower end and a draft outlet at the upper end, and a door at the side of the casing for supplying fuel to the fire box, a partition extending inwardly from the opposite side of the casing toward the door and overlying substantially one-half of the fire-box, a wall in the casing extending upwardly from the inner edge of said partition and terminating below the draft outlet, so as to divide the interior of the casing between the fire box and draft outlet into two passageways, means extending outwardly from the center of said wall to the wall of the casing so as to divide the passageway above said partition vertically into two parts and a valve at the upper end of the said wall for optionally obstructing or causing circulation through the two part passageway from the fire box to the draft outlet of the casing.

5. In a stove, the combination of a casing having a fire box at the lower end and a draft outlet at the upper end, support- ,ing means extending inwardly from the wall of the casing above the fire box, and a horizontal partition with vertical partitions thereabove supported by the said 'means for dividing the casing above the fire box into a plurality of vertical passageways, and adjustable means for affording circulation directly from the fire box to the draft opening or consecutively through said passageways.
